Callsigns and numbers recognition was improved for Catch word in contest mode option.

V2.76

QPSK-63 mode is supported now.

V2.75

An option Use mouse wheel for tuning was made.

Some minor bugs were fixed.

V2.70

Some issues occurred under Windows Vista were fixed.

Default working directory of software is located in Application Data(ProgramData under Vista) in place of Program Files now.

Command line parameter /F can define configuration file name now.

/S parameter of command line is not used now.

V2.60

BPSK-125 mode receiving and transmitting were made.

TrueTTY can cooperate with another software as COM-server (ActiveX object) now.

V2.57

Invisible buffer is not used now. Receiving window contains all received symbols until it is manually cleared.

Beacon regulator defines not period, but pause between transmissions now.

V2.56

Minor improvements of RX window text displaying were made.

New options were made:
Setup / Other / Do not strip received NIL symbols from capture file and exchange channels;
Setup / Other / Put time marks to a capture file;
Setup / MOX & Beacon / Beacon off if my callsign ... is received;
Setup / MOX & Beacon / Beacon off if any callsign is received twice.

Some options were moved from the Setup / Interface page to the Setup / MOX & Beacon.

V2.55

Documentation was updated.

W1GEE PTT-interface is supported in LPT/N6TR mode now.

V2.53

The Fast Macros Edit window is shown after right mouse button click at macro button now.

The `[tn] macrosequence was made. In MFSK16 and MFSK8 modes several idle
symbols and then continuous carrier (about 2 seconds) are transmitted
by this macrosequence to help to tune to a signal. In another mode just
an idle symbol is transmitted.

V2.52

MultiFSK-8 mode receiving and transmitting were made.

Color highlighting of received callsigns was made.

Some internal improvement were made.

V2.50

The Show Omni-Rig Setup button at the Setup / Tuning page was made.
This button can be used to activate Omni-Rig setup dialog.

Fine-tuning screen buttons can be used for TX frequency changing now. TX frequency is changed by these buttons if right mouse button is used or
Ctrl key is pressed.

V2.40

A problem of frequency control of some RIG types was fixed.

When the Setup / Interface / AFC at mouse click option is selected
a fast AFC is made by click at spectrogram, but it is not made by click at frequency ruler below now.

V2.39

The option Follow VFOB by VFOA with offset (at Setup / Tuning page)
was made. In this mode VFOB frequency is tuning to VFOA frequency with
given offset automatically. This option is useful if transceiver can not
use narrow-band filters in SSB mode. For example, you can receive in
CW or FSK mode (with VFOA) and transmit in SSB (with VFOB) now.

V2.38

A minor bug with TX marks drawing in waterfall mode was fixed.

The mode of automatic transceiver frequency control can be switched on at
Setup / Tuning page. In this mode transceiver radio frequency
is changed to consist RX frequency to TX frequency. Auto-tuning is made
after click on spectrogram. Tuning can be made by RIT or by VFO according
selected option. Take to attention that not every transceiver has
programmable RIT. In this case auto-tuning
by RIT is impossible. Tuning is made via OmniRig software interface.
Hamport software uses this interface also.

V2.30

TrueTTY can send information about used mode to logger now.
See Setup / Other / Send Mode to logger when mode was changed,
Setup / Other / Send Mode to logger together with callsign and
Setup / Other / Send mode ... as ... options.

V2.26

Fast squelch in AX25 mode was made.

V2.25

AFC has two parameters now.
The first parameter is local deviation in hertzs, i.e. maximal deviation from current frequency.
Second parameter is global deviation in hertzs, i.e. maximal deviation from last user-selected frequency.
User-selected frequencies are shown at spectrogram or waterfall by short thin lines .

V2.24

MultiFSK decoder was improved.

V2.23

AX25 decoder was rewritten. Noise-immunity was great improved in HF-PACKET and slightly improved in UHF-PACKET.

V2.22

V2.21

V2.20

User can select optimal or wide filters via Filters menu in RTTY and ASCII modes now.
Wide filters can be useful to decoding signals corrupted by polar flutter. Use optimal filters in all another cases.

V2.19

RTTY and ASCII decoder was rewritten to improve decoding quality.

V2.10

The documentation was updated.

Auto-recognizing of callsigns and control numbers was improved in contest mode.

V1.95

TrueTTY can exchange receiving and transmitting data to another software via additional COM-port now. So, TrueTTY can emulate hardware modem or TNC.
The Setup / Data Exchange Interface menu selects COM-port used for this purpose.
So, with two com ports (in single computer or in two computers) connected via null-modem cable, you can use TrueTTY with another terminal software intended for hardware modem using.
For example, you can try to use TrueTTY with WF1B contest software (though I prefer AALog). A speed of data exchange via COM-port is 9600 bauds. See null-modem cable schematics in NULL-MOD.GIF file.
If you are using COM-port for PTT interface but don't use it for FSK, you can use the same port for data exchange also.
Software COM-port emulator can be used also. I have used VSPD virtual COM-port driver from http://www.mks.zp.ua with success.

V1.92

The File / Open Buffer in Notepad
command was made. It saves receiving buffer in a temporary file and opens this file by a text editor. Then you can view this file or print it. The hotkey of this command is Ctrl-N. This command is available in registered version of the software only.

A bug with the List index out of bounds message appearing during editing of text to transmit was fixed, I hope.

V1.91

The Setup / Catch Words in Contest Mode option was made. In this mode software doesnt use popup-menu to catch word to logger.

TrueTTY recognize callsign or control number automatically.

The Setup / Beacon Off At Mouse Click option was made. If this option is enabled, beacon is switched off by mouse click on spectrogram, RX window or input window or by key pressed in the input window.

The Setup / Continuous Carrier While Idle option was made.

If this option is enabled, TrueTTY doesnt use idle symbols in RTTY and ASCII modes.

Some minor bugs were fixed.

V1.90

UHF-PACKET (1200 Baud) decoding was made.

The Grid option was added to context menu to transfer received QTH-locator to logger.

The 182 Hz shift value was added to the shift menu. This value is optimal for interchannel crosstalk reducing at 45.45 Baud speed.

V1.88

FSK-demodulator was fully rewritten.

V1.87

FSK-demodulator was rewritten. So decoding of RTTY, ASCII, AMTOR and AX25 should be improved now.

V1.85

To avoid problems with macrosequences, the ] symbol is treated as word separator in Send Whole Word Only mode.

Minor bug with macro button drawing in system with large font was fixed.

V1.83

AFC algorithm was improved for speed above 75 Baud or shift below 85 Hz. This algorithm is used in AMTOR and AX25 modes also.

The Setup / AFC At Mouse Click option was made. When is option is selected TrueTTY make fast AFC to near station after mouse click on spectrogram regardless of the AFC button state.

The Send Whole Word Only option was made. In this mode software doesnt start to transmit next word until space symbol or line feed is entered.

New Beacon button switch on beacon mode now. In this mode Alt-F12 macro is executed periodically. The period is defined by the regulator on the left of the Beacon button. The shortcuts for Beacon button are Alt-B and Ctrl-B. The macrosequences ~[bon]and `[bon] switch beacon mode on, the macrosequences ~[boff]and `[boff] switch beacon mode off.

V1.81

V1.78

An old internal bug was fixed.

V1.77

The old bug with Alt-T keystroke was fixed. Sometimes it was necessary to click on them twice to switch transmitter on.

If there are several sound cards in a computer, you can select the card by the SoundCardNumber parameter of [RTTY] section of TRUETTY.INI file. For example SoundCardNumber=0,SoundCardNumber=1, etc.

V1.73

After ~[ni...] macro execution new field value is transferred to logger.

After Clear button pressing or ~[ce] macro execution new fields values are transferred to logger.

The Setup / Use Other Field As menu assigns alternative meaning to Other edit field. This meaning is used to catch words from RX window and to transfer data to logger.

V1.72

The problem with spontaneous switching of keyboard layout during transmission was fixed.

Macrosequences for logger control were made:

~[lc]or `[lc]  to clear all fields, except Date, Band and Mode in the New QSO window of the AALog;

~[lt]or `[lt]  to set current time and date in the New QSO logger window;

~[ls]or `[ls]  to save QSO into the log;

~[lts]or `[lts]  to set current time and date and save QSO.

Macrosequences for increment of numbers in the edit fields were made:

~[nic]or `[nic]  to increment a number in the Call field;

~[nir]or `[nir]  to increment a number in the RST field;

~[nin]or `[nin]  to increment a number in the Name field;

~[nio]or `[nio]  to increment a number in the Other field.

The menu option Setup / Catch Word by One Mouse Click was made. When this option is enabled, you can catch a word from RX window by single mouse click, not double-click. But you still can select the part of the text by a mouse dragging.

The - char is the word delimiter now.

TrueTTY can transfer received symbols to another software and get symbols to transmit from another software now. Data exchange can be made by DXSOFTEX.DLL library. See http://www.dxsoft.com/dxs-exch.zip for details.

V1.70

Some minor bugs were fixed.

V1.68

More accuracy timing control in AMTOR mode was made.

Two parameters were added to correct sound card sampling rate variation against nominal frequency (11025 Hz). The first is SamplingFreq parameter of the TRUETTY.INI file, the second is /s parameter of command line. Any of these parameters define real sampling frequency. When both parameters are defined, the command line parameter has priority.

A bug with COM-port FSK output was fixed  some transmitted symbols were lost before.

V1.66

Bug in the Edit Macros procedure was fixed.

V1.65

File / Send Text File command was added.

Three pins of LPT-port (D1,D2 and D5) are used to PTT-control now. This feature permits user to select pin that has low voltage level after computer reboot and make program compatible with W1GEE interface.

V1.62

V1.61

Much more convenient Input window was made. Sent symbols are not deleted from this window immediately now. They just change color to the same color as Sent window text. Transmitted text are deleted from Input window after Line Feed symbol transmitting.

V1.60

Release version. Documentation was updated.

Setup / English/Russian Ext. Charset option for used alphabet in RTTY and AMTOR modes was made. When this option is selected, Russian/English shift is switched by the same way that Russian commercial station use.

~[cwtText]  to switch TX on, sent Text by Morse code and continue transmit with current mode;

It is necessary to use underline symbol (_) in place of space in Text sequence.

When Backspace handling is switching on, backspace symbols are right handled in Sent window now.

V1.53

AMTOR-FEC(SITOR-B) receiving was made. Try the Fast Sync option, you will like it. To receive broadcast FEC, the Normal/Reverse button must be in the same position as for RTTY, that is Normal in USB and Reverse in LSB. To receive SELFEC, switch this button in another position and switch on the Fast Sync option.

V1.52

In ASCII-7and ASCII-8 modes NIL symbol is transmitted before each Space or CR symbol. It was made for better bit synchronization.

V1.51

ASCII-7and ASCII-8 modes were implemented. I think that modes are not less convenient for QSO than PSK31, but they are not such sensitive to tuning accuracy and propagation conditions.

Backspace symbols handling was made in PSK and ASCII modes. That feature can be switched off by Setup / Backspace Handling menu.

Support of Swedish version of Baudot code was made in RTTY mode. It is switched on by Setup / Swedish Charset menu.

V1.50

Release version. Documentation was updated.

Bug with some Russian letter transmitting in RTTY-mode was fixed.

Minor change in QPSK31-receiving was made.

V1.42

QPSK31 transmitting was made.

V1.41

In RTTY mode two shift values were added (85 Hz and 22 Hz).

QPSK31 receiving was made (transmitting is not implemented yet).

V1.39

Submenu Setup / Time Zone was made. It is not necessary to edit UTCoffset manually now.

New submenu Setup / Fonts and Colors was made.

File / Open Capture File command opens capture-file for received symbols. If file exist, new symbols are appended to it.

File / Close Capture File command closes capture-file.Capture-file state is shown in status-line. Hotkey for capture on/off commands is Alt-L.

New Alt-S hotkey was made.

New macrosequences were made:

~[crx]  to clear RX buffer;

~[csnt]  to clear sent symbols window.

V1.38

There are 37 keyboard macros now.

Optional UTCoffset parameter can be used in [RTTY] section of TRUETTY.INI file. This parameter define difference between UTC and local time in minutes. If UTCoffset parameter is defined, program ignore information about Time Zone from operational system.

V1.37

PSK31 decoding procedure were highly changed to improve decoding.

V1.35

Release version. Documentation was updated, minor program changes were made.

V1.32

Option Show Sent Symbols In RX Window was made (Setup / View / Show Sent Symbols In RX Window).

V1.31

COM-ports are handled via Windows API now, so COM-portPTT-interface should work on Windows NT too.

TxD out of COM-port can used for FSK-control of transceiver (in RTTY mode, surely).

V1.30

Release version. Minor program and documentations changes were made.

V1.29

Beta-version with PSK31 (BPSK mode) support.

V1.26

Problem with Rx buffer overflow was fixed. When Rx buffer are grown to about 20 Kbytes, part of data is moved into invisible buffer. By Save Buffer command both part of Rx buffer (invisible and visible) are saved.

Russian code page was corrected.

V1.25

Working sound band is 300 3000 Hz now.

More optimal filters were made.

V1.20

Documentation was updated.

Minor changes were made.

The installer was added.

V1.15

Option Unshift On Space was made. In that mode Rx symbol shift is switched to Letters after receiving Space or Line Feed symbol.
